Public Member Functions

const TargetDescription *const getDescription (unsigned nodeId, bool *ok=0) const
 Return the description of a node and set ok to true, if provided; if invalid, return 0 and set ok to false.
unsigned getNodeId (const std::wstring &name, unsigned preferedId=0, bool *ok=0) const
 Return the id of the node corresponding to name and set ok to true, if provided; if invalid, return 0xFFFFFFFF and set ok to false. If several nodes have this name, either return preferedId if it exists otherwise return the first found.
std::wstring getNodeName (unsigned nodeId) const
 Return the name corresponding to a node identifier; if invalid, return the empty string.
unsigned getVariablePos (unsigned nodeId, const std::wstring &name, bool *ok=0) const
 Return the position of a variable and set ok to true, if provided; if invalid, return 0xFFFFFFFF and set ok to false.
unsigned getVariableSize (unsigned nodeId, const std::wstring &name, bool *ok=0) const
 Return the length of a variable and set ok to true, if provided; if invalid, return 0xFFFFFFFF and set ok to false.
void processMessage (const Message *message)
 Process a message and reconstruct descriptions if relevant.
void reset ()
 Reset all descriptions, for instance when a network was disconnected and is reconnected.
virtual ~DescriptionsManager ()
 Virtual destructor.

Protected Types

Protected Member Functions

void checkIfNodeDescriptionComplete (unsigned id, const NodeDescription &description)
 Check if a node description has been fully received, and if so, call the nodeDescriptionReceived() virtual function.
virtual void nodeDescriptionReceived (unsigned nodeId)
 Virtual function that is called when a node description has been fully received.
virtual void nodeProtocolVersionMismatch (const std::wstring &nodeName, uint16 protocolVersion)
 Virtual function that is called when a version mismatches.

Detailed Description

This helper class builds complete descriptions out of multiple message parts. For now, it does not support the disconnection of a whole network nor the update of the description of any node
